Lattice Semiconductor
IPexpress™
The user can access the sysDSP block via the IPexpress tool, which provides the option to configure each DSP
module (or group of modules) or by direct HDL instantiation. In addition, Lattice has partnered with The Math-
Works
mond and ispLEVER to dramatically shorten the DSP design cycle in Lattice FPGAs.
Optimized DSP Functions
Lattice provides a library of optimized DSP IP functions. Some of the IP cores planned for the LatticeECP2/M DSP
include the Bit Correlator, Fast Fourier Transform, Finite Impulse Response (FIR) Filter, Reed-Solomon Encoder/
Decoder, Turbo Encoder/Decoder and Convolutional Encoder/Decoder. Please contact Lattice to obtain the latest
list of available DSP IP cores.
Resources Available in the LatticeECP2/M Family
Table 2-9 shows the maximum number of multipliers for each member of the LatticeECP2/M family. Table 2-10
shows the maximum available EBR RAM Blocks in each LatticeECP2/M device. EBR blocks, together with Distrib-
uted RAM can be used to store variables locally for fast DSP operations.
